Agriculture is considered to be a major source of greenhouse gas emissions. The main activity of gas generation is livestock farming, especially cattle and pig farming, according to many studies conducted internationally. The main greenhouse gases are water vapors, methane, carbon dioxide, ammonia. Methane emitted in the atmosphere is considered to be more harmful than carbon dioxide, accelerating the global warming phenomenon. Methane emissions from the livestock sector result from metabolic processes and manure. Ammonia is another gas resulting from the growth of animals that, in high concentrations, affect the health of the population, the animals and the environment. Ammonia emissions are influenced by factors such as animal feed composition, temperature, humidity, livestock shelter, etc. Greenhouse gases are the main cause of global warming, an international problem for which solutions are still being sought. The phenomenon of global warming implies serious environmental, population and animal effects, and agriculture is one the cause of the rise in annual average temperature. This is why the emphasis is on identifying sources of air pollution and ways to mitigate the adverse effects of the agricultural sector. The purpose of this study is to estimate emissions into the air at national level in the cattle and pig breeding sector. The official data provided by the National Institute of Statistics was used to carry out this study. Based on these data, emissions were estimated for each calendar year between 1990 and 2016, and then the results were interpreted to track the evolution of gas emissions from this sector. It has been noted that Romania has experienced a regression in livestock farming nationwide according to the data provided by the National Institute of Statistics therefore the amount of greenhouse gas emissions from the zootechnical sector is significantly diminishing.
